将两个不同的对象自动装配到一个spring bean

I am new to spring MVC and trying to add fields in existing form validate them. once the validation is complete, I need to map the data entered in form to a different object. The configuration of the spring bean is something like below.

我是Spring MVC的新手,并试图以现有形式添加字段来验证它们。验证完成后,我需要将表单中输入的数据映射到不同的对象。 spring bean的配置如下所示。

<bean id="SampleController"
    class="com.abcd.controller.SampleController"
    parent="AbstractxyzMlsController">
    <property name="formView"            value="abc/my_view" />
    <property name="highLightedTab"      value="DataRequirement" />
    <property name="commandName"         value="dataRequirement" />
    <property name="commandClass"        value="com.abcd.dataRequirementResponse" />
    <property name="validator"                            ref="DataAcceptanceValidator" />
</bean>

From the form of above spring bean configuration, I need to modify it accept few more fields and put them under a different object. I cannot use the same object as in the commandclass mentioned above. And i also need to validate the fields i add in the form. I see that the current validator accepts the object DataRequirement alone.

从上面的spring bean配置的形式,我需要修改它接受更多的字段并将它们放在不同的对象下。我不能使用与上面提到的命令类相同的对象。我还需要验证我在表单中添加的字段。我看到当前的验证器单独接受对象DataRequirement。

Do i need to come up with a different validator? Also How do i add the second object where I am going to put the fields in?

我需要提出一个不同的验证器吗?另外我如何添加第二个对象,我将把字段放在哪里?

Sorry if the question was dumb. Just trying to understand and implement.

对不起,如果问题是愚蠢的。只是想了解和实施。

It is impossible to have multiple objects for same form.

对于相同的形式,不可能有多个对象。

But there is the way, you can use multiple objects like this :

但有方法,你可以使用这样的多个对象:

Backend :

public class FormObject() {
    Class1 class1Object;
    Class2 class2Object;
    //Getter and setter
}

Frontend :

<form:form
  action="../someAction"
  method="post" commandName="formObject">

  ...
  <form:input type="text" path="class1Object.property"/>
  ...
  <form:input type="text" path="class2Object.property"/>
  ...
</form:form>

There is a concept called jsr303 and hibernate validator. with help of Binding results we can get all the error messages. Refer the following link.

有一个名为jsr303和hibernate验证器的概念。在Binding结果的帮助下,我们可以获得所有错误消息。请参阅以下链接。
